Underwater Universe

The Underwater Universe generates three types of deadly waves, each bigger and more destructive than the last: Rogue, Monster and Tsunami. This episode will progress from big to bigger waves and explore how these killers are born and what makes each unique. We end the hour with the biggest recorded impact wave in Earth's history: a mega Tsunami over a hundred feet high destroying everything in its path. How did it happen? How did the planet survive? And could we be hit by a wave that big again? (texte officiel du distributeur)
